IMPROVEMENT IN WELL-TUBING.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, Lnwrs F. RIDER and Jens W. Funny, of Hornellsville, in the county of Steuben, State of New York, have invented certain new-and useful Improvements in Point for driving the tubular wells and shields to prevent quieksand and clay from filling up the water'pipe; and the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a. part of this specification, in whicht Figure 1 represents the point, shield, ands-lower section of thetubing, all together in position for driving.

Figure 2 shows the same parts as fig. 1, the point detached, with shield drawn up.

-Figure 3 shows the shield detached from the lower section of pipe.

Figure 4 shows another form of the point.

Our invention consists in the construction of the point and the outside band orshield, the point being provided with square cutting-edges to out its way through hard earth or sand-stone straighter than points which only force the earth from the centre of the'poinflthe shield being provided witlrribs on the outside to prevent it turning while being driven; also in the mode of connecting the shield with the pipe so as to carry the shield down with the pipe and point until the depth required is nearly reached, when the pipe, by being turned in-the shield and on'the point, can be driven further, leaving the shield above the openings to admit the flow of water- That others may make and use our invention we will describe it in detail, referring to the several figures in the drawings, and to the letters marked thereon.

We make our pointsA of cast iron, with projecting sharp cutting-edges a a a a at the bottom. The point A is provided with, a stem, B, to enter the lower section of the water pipe C, it having a ledge or ofllset, b b,

suficient' to protect both the end of the tube or water pipe C and the shield or barrel D, which is placed on to the lower joint of the pipe 0, and held from slipping up, when the tube is being driven, by a half-inch steel pin put through, extendinginto slots 0 c on both sides of the shield D, the ends of the projecting pin d holding on the ledge c c on both sides, as the tube is being driven, so as to carry the shield down with it, the shield D being provided with two or morelongitudinal ribs ff on the outside, runnin parallel with the shield to pre'.

13 vent it from turning while the tube is being driven. When the tubing has been driven to near the required depth, by turning it so as to bring the pin d oil' .the ledges e e the pipe C can be driven further, leaving ,the shield D above the point asufiicient distance to uncover the openings It]; It It on the pipe 0 to admit the flow of water. Fig. 4 is another mode of construction for. the metallic points, which is preferable to the other in hard clay soil.

Having'thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The point A, as constructed, with its projecting cutting-edges a a d on the under side, combined'wi'th the lower end of thetube C, with its steel pin d to hold the barrel or shield D on the outside of the pipe while being driven, substantially as herein described for the purposes set forth.

In testimony whereof we hereunto subscribe our names" in the presence of- LEWIS F. RIDER, JOHN W. FERRY.
